Abstract: Technologies are described for performing replication of data within a database environment having a source node and a replica node. The source node executes a database operation on at least one database table stored by the source node. The source node asynchronously sends the database operation to the replica node. A prepare commit request is synchronously sent from the source node to the replica node. The source node receives a synchronous precommit acknowledgement from the replica node. The precommit acknowledgement indicates that the database operation was executed at the replica node. The source node commits a transaction associated with the database operation.

Abstract translation: 描述了用于在具有源节点和复制节点的数据库环境内执行数据复制的技术。 源节点对源节点存储的至少一个数据库表执行数据库操作。 源节点将数据库操作异步发送到副本节点。 准备提交请求从源节点同步发送到副本节点。 源节点从副本节点接收同步预提交确认。 预提交确认指示数据库操作已在副本节点上执行。 源节点提交与数据库操作关联的事务。
